Insulators Ceramics engineers are testing a new formulation for the material used to make insulators for power lines. They will try baking the insulators at four different temperatures, followed by either slow or rapid cooling.
They want to try every combination of the baking and cooling options to see which produces insulators least likely to break during adverse weather conditions.

b) How many factors are there?
c) How many treatments are there?
d) What is the response variable?
Question 2
A researcher wants to compare the performance of three types of pain relievers in volunteers suffering from arthritis.
Because people of different ages may suffer arthritis of varying degrees of severity, the subjects are split into two groups: under 60 and over 60. Subjects in each group are randomly assigned to take one of the medications. Twenty minutes later they rate their levels of pain. This experiment
A) is completely randomized.
B) has two factors, medication and age.
C) uses matched pairs.
D) has one factor (age) blocked by medication type.
E) has one factor (medication) blocked by age.
